Aline Lerner
Aline Lerner is the founder and CEO of interviewing.io, an anonymous technical interview platform that has hosted over 100,000 practice sessions and helped engineers get hired at companies like Facebook, Uber, Dropbox, and Lyft. A former MIT engineer who spent years as a professional cook before returning to tech, she ran hiring at Udacity, launched her own recruiting firm, and discovered through data that resume typos predicted candidate quality better than Ivy League credentials. Her data-driven writing on the dysfunction of technical hiring has been read by millions and featured in Forbes, the Wall Street Journal, and Fast Company (which named her one of the 100 Most Creative People in Business in 2018). In January 2025, she co-authored Beyond Cracking the Coding Interview, the official sequel to the seminal CtCI book, co-written with Gayle Laakmann McDowell.
